A procedure may require a gouge process to remove steel backing, burn off weld tabs or back gouge. Gouging is necessary for many tasks related to welding when the operator is trying to remove material to get to clean metal. The most obvious use of gouging is to remove large amounts of metal or welds that need to be repaired.

To be certain of removing the unfused land, 'back gouging' the root and filling the groove with sound weld metal is generally carried out. Backgouging, or removal of the unfused land, can be done by any of the conventional metal removal techniques; machining, arc air gouging, chipping, grinding etc (Fig.2). Of these methods, arc air gouging is ...

The air carbon arc cutting process (CAC) is used to cut metal, to gouge out defective metal, to remove old or inferior welds, for root gouging of full penetration welds, and to prepare grooves for welding. Air carbon arc cutting is also used when slightly ragged edges are not objectionable. The area of the cut is small and, since the metal is ...

Proper dressing will help maintain a consistent and even surface on the wheel, preventing it from gouging the part. Incorrect Wheel Speed: If the surface grinder's wheel speed is too high, it can lead to gouging. High speeds generate excessive friction and heat, causing the wheel to wear unevenly and dig into the part.
